Preliminary identification of earthquake triggered multi-hazard and risk in Pleret Sub-District (Yogyakarta, Indonesia)

Geo-spatial Information Science, 2021
Yogyakarta is one of the large cities in Central Java, located on Java Island, Indonesia. The city, and the Pleret sub-district, where the study has taken place, is prone to earthquake hazards, because it is close to several seismically active zones ...

Field relations among coseismic ground motion, water level change and liquefaction for the 1999 Chi‐Chi (M_w = 7.5) earthquake, Taiwan

Geophysical Research Letters, 2003
Field‐based, basin‐wide relations are discovered among coseismic ground motion, water‐level change and liquefaction induced by the 1999 (Mw = 7.5) Chi‐Chi earthquake, Taiwan. The relations imply thresholds of 4.4 m/s2 and 0.6 m/s in the spectral acceleration and velocity at 1 Hz, respectively, below which pore pressure does not change appreciably and ...

The survey and mapping of sand-boil landforms related to the Emilia 2012 earthquakes: preliminary results

Annals of Geophysics, 2012
Sand boils, which are also known as sand blows or sand volcanoes, are among the most common superficial effects induced by high-magnitude earthquakes. These generally occur in or close to alluvial plains when a strong earthquake (M >5) strikes on a ...

Liquefaction-induced large-scale ground deformation triggered by the 7 January 2025 MS 6.8 Dingri earthquake: characteristics and formation mechanisms

Dizhi lixue xuebao
Objective  In liquefaction-susceptible geological settings, the spatial superimposition of earthquake-induced liquefaction and coseismic fault rupture renders the genetic attribution of surface deformation highly ambiguous, yet systematic field ...

Coherence Difference Analysis of Sentinel-1 SAR Interferogram to Identify Earthquake-Induced Disasters in Urban Areas

Remote Sensing, 2018
This study proposes a workflow that enables the accurate identification of earthquake-induced damage zones by using coherence image pairs of the Sentinel-1 satellite before and after an earthquake event.

A case-based reasoning method of recognizing liquefaction pits induced by 2021 MW 7.3 Madoi earthquake

Earthquake Research Advances, 2023
Earthquake-triggered liquefaction deformation could lead to severe infrastructure damage and associated casualties and property damage. At present, there are few studies on the rapid extraction of liquefaction pits based on high-resolution satellite ...

Complex Shear Partitioning Involving the 6 February 2012 M_W 6.7 Negros Earthquake Ground Rupture in Central Philippines

Geosciences, 2020
A 75 km-long, generally NE-striking ground rupture associated with the 6 February 2012 MW 6.7 (Mb 6.9) Negros earthquake was mapped on the eastern side of Negros Island, Philippines.

Impact of 2019 Earthquakes on Shallow Aquifers in Northern sub-Himalayan Pakistan: A Detailed Analysis of Mirpur and Surrounding Areas

Geofísica Internacional
In 2019, a series of earthquakes struck the northern sub-Himalayan region of Pakistan, with the Mirpur earthquake triggering extensive coseismic liquefaction-induced surface deformations, such as sand blows, ground failure, and lateral spreading along ...

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.

Holocene Slip Behavior and Shallow Structure of the Milun Fault at the Collision–Subduction Transition, Eastern Taiwan

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.
The Milun Fault forms the northernmost onshore segment of the Longitudinal Valley fault system, a plate‐boundary suture between the Eurasian and Philippine Sea plates in eastern Taiwan, and poses a significant seismic hazard to Hualien City. Despite destructive earthquakes in 1951 and 2018, the shallow structure, long‐term slip behavior, and ...
